You will also need to express terms in the form a{x^n} where a and n are constants.

Examples in the video

Express the following in the form a{x^n}:

  1. \dfrac{1}{{{x^4}}}
  2. \dfrac{2}{{{x^5}}}
  3. \dfrac{3}{{5{x^5}}}
  4. 5\sqrt x
  5. \dfrac{{4\sqrt[3]{x}}}{5}
  6. \dfrac{3}{{\sqrt x }}
  7. \dfrac{3}{{5\sqrt[4]{x}}}
  8. \dfrac{2}{{5\sqrt[4]{{{x^3}}}}}
